ooking at an NVIDIA gaming GPU but can't decide on the GeForce Go 7900 GTX or the GS? We pit two similarly configured Dell XPS M1710 laptops against each other to test everything from performance to power consumption to see which GPU you should get.

The GeForce Go 7900 GTX is a real beast and it has enough headroom to play games at a stunning 1920x1200. This makes the GeForce Go 7900 GTX a better candidate for gaming on larger connected displays than the Go 7900 GS. For mobile gamers who want the fastest or consumers who plan on using their laptop for years to come (i.e. something more "future-proof"), then a laptop with the Go 7900 GTX is the way to go thanks to the extra shader and ALU processors, the 512MB RAM buffer and the higher clock speeds.

Both the GeForce Go 7900 GTX and GeForce Go 7900 GS are superb graphics solutions for the serious mobile gamer who don't want to compromise on quality and level of detail. These GPUs are available from many different laptop manufacturers including Dell, Toshiba, Alienware, Voodoo, and ROCK.
